Abstract

A canopy running channel, a sunroof assembly, and a vehicle are provided. The canopy running channel includes a hollow tube and an end member. The hollow tube includes an outer tube and an inner tube. The end member includes a first end-member and a second end-member. Both one end of the outer tube and one end of the inner tube are connected to the first end-member, and the other end of the inner tube is connected to the second end-member. The end member is configured to be mounted on sunroof glass, the end member includes an upper member configured to be away from the sunroof glass and a lower member configured to be close to the sunroof glass. The upper member defines a fitting hole in communication with the hollow tube, and the lower member has an extension portion configured to be mounted on the sunroof glass.

First claim

What is claimed is:

1 . A canopy running channel, comprising a hollow tube and an end member, wherein the hollow tube comprises an outer tube and an inner tube, the end member comprises a first end-member and a second end-member, both one end of the outer tube and one end of the inner tube are connected to the first end-member, and the other end of the inner tube is connected to the second end-member; the end member is configured to be mounted on sunroof glass, the end member comprises an upper member configured to be away from the sunroof glass and a lower member configured to be close to the sunroof glass, and a surface of the upper member configured to be away from the sunroof glass is an upper surface; and the upper member defines a fitting hole in communication with the hollow tube, and the lower member has an extension portion configured to be mounted on the sunroof glass.

2 . The canopy running channel of claim 1 , wherein the extension portion is provided with a buffer portion configured to be connected to the sunroof glass.

3 . The canopy running channel of claim 1 , wherein the upper member is provided with a first positioning portion on the upper surface of the upper member, and the first positioning portion is configured for positioning in a mold.

4 . The canopy running channel of claim 3 , wherein the first positioning portion is a recess or a boss.

5 . The canopy running channel of claim 1 , wherein the extension portion is further provided with a second positioning portion configured for positioning in a mold.

6 . The canopy running channel of claim 5 , wherein the second positioning portion is a positioning hole.

7 . The canopy running channel of claim 2 , wherein a material of the buffer portion is a thermoplastic elastomer (TPE) material.

8 . The canopy running channel of claim 1 , wherein the upper member defines a mounting hole on the upper surface of the upper member, and a nut is provided in the mounting hole.

9 . The canopy running channel of claim 8 , wherein the end member, the hollow tube, and the nut are integrally injection-molded.

10 . A sunroof assembly, comprising:
sunroof glass; a motor mounting portion mounted on the sunroof glass; two canopy running channels, wherein each of the two canopy running channels comprises a hollow tube and an end member, the hollow tube comprises an outer tube and an inner tube, the end member comprises a first end-member and a second end-member, both one end of the outer tube and one end of the inner tube are connected to the first end-member, and the other end of the inner tube is connected to the second end-member; the end member is mounted on the sunroof glass, the end member comprises an upper member away from the sunroof glass and a lower member close to the sunroof glass, and a surface of the upper member away from the sunroof glass is an upper surface; and the upper member defines a fitting hole in communication with the hollow tube, and the lower member has an extension portion mounted on the sunroof glass; wherein the two canopy running channels are fixedly connected to the sunroof glass by injection-molding an encapsulation, one of the two canopy running channels is disposed at one end of the motor mounting portion, and the other of the two canopy running channels is disposed at the other end of the motor mounting portion; and two guiding rails, wherein one end of each of the two guiding rails is aligned with one of two second end-members, the two guiding rails are disposed in parallel, and each of the two guiding rails and each of the canopy running channels cooperatively define a tube for movement of a cable.

11 . The sunroof assembly of claim 10 , wherein a hollow tube is provided with a plurality of process clamping portions, the plurality of process clamping portions are spaced apart from one another sequentially along an arrangement path of the hollow tube, and the plurality of process clamping portions are exposed beyond the encapsulation.

12 . The sunroof assembly of claim 11 , wherein the hollow tube comprises a first straight tube section connected to the motor mounting portion, a second straight tube section disposed in a guiding direction of the guiding rail, and a curved tube section for connecting the first straight tube section and the second straight tube section, at least one of the plurality of process clamping portions is disposed in the first straight tube section, and at least one of the plurality of process clamping portions is disposed in the curved tube section.

13 . The sunroof assembly of claim 11 , wherein a length of each of the plurality of process clamping portions is B, and satisfies: 10 mm≤B≤20 mm.

14 . The sunroof assembly of claim 10 , wherein a concentricity error between a fitting hole of one of two first end-members in communication with an outer tube and a fitting hole of the other of the two first end-members in communication with an inter tube is +0.3 mm.

15 . The sunroof assembly of claim 10 , wherein a concentricity error between a fitting hole of each of the two second end-members and one of the two guiding rails close to the each of the two second end-members is +0.3 mm.

16 . The sunroof assembly of claim 10 , wherein a hollow tube is wrapped in the encapsulation, and a lower member is wrapped in the encapsulation.

17 . The sunroof assembly of claim 10 , wherein the other end of an outer tube is exposed beyond the encapsulation.

18 . The sunroof assembly of claim 10 , wherein an interference amount between the buffer portion and the sunroof glass is A, and satisfies: 1 mm≤A≤2 mm.

19 . A vehicle, comprising a motor and a sunroof assembly, wherein the motor is mounted at the motor mounting portion, and the sunroof assembly comprises:
sunroof glass; a motor mounting portion mounted on the sunroof glass; two canopy running channels, wherein each of the two canopy running channels comprises a hollow tube and an end member, the hollow tube comprises an outer tube and an inner tube, the end member comprises a first end-member and a second end-member, both one end of the outer tube and one end of the inner tube are connected to the first end-member, and the other end of the inner tube is connected to the second end-member; the end member is mounted on the sunroof glass, the end member comprises an upper member away from the sunroof glass and a lower member close to the sunroof glass, and a surface of the upper member away from the sunroof glass is an upper surface; and the upper member defines a fitting hole in communication with the hollow tube, and the lower member has an extension portion mounted on the sunroof glass; wherein the two canopy running channels are fixedly connected to the sunroof glass by injection-molding an encapsulation, one of the two canopy running channels is disposed at one end of the motor mounting portion, and the other of the two canopy running channels is disposed at the other end of the motor mounting portion; and two guiding rails, wherein one end of each of the two guiding rails is aligned with one of two second end-members, the two guiding rails are disposed in parallel, and each of the two guiding rails and each of the canopy running channels cooperatively define a tube for movement of a cable.
